Subject: Compiling/computing known lexicons by age/education
Question: One of my acquaintances has a PhD in Linguistics; however, he's not
available to answer my questions at this time.

How do linguists (and others?) find out how many words different
groups (distinguished by age and education) know?

Thank you!

Sincerely and respectfully,

Reply: As Professor Sampson points out, there are many methods for estimating the size of
lexicon across an age range or within educational progress ranks, not a single well-
standardized method.

Notice also that some methods may ask for open-ended responses (such as Sampson's
suggested "provide a definition"), where others ask for responses from a closed set
("which of the following four words is a synonym for <target word>...."). From other
research on cognition and psycholinguistics, we know that recognition is easier than
recall. In addition you've got a 25% chance of being correct on a closed set of 4
possible responses, whereas an open-ended answer has no guarantee of success - a
much higher bar, if you will - a more restrictive measure.

In what context did you see some estimate for size of lexicon? Did you ask yourself
whether it was a comparable estimate to another, perhaps looking at quite a different
age group or otherwise distinct population? There may be 2 or more different methods
in use.

Notice also that reading vocabulary may be quite different from speaking vocabulary.
Surely there are many terms that you feel comfortable meeting on the printed page
which you might never use in your own speech or writing.
